Carroll County, County administrative division in northwestern Illinois, United States

Carroll County is an administrative division in northwestern Illinois encompassing multiple townships situated between the Mississippi River and Rock River valleys. The seat of government is Mount Carroll, which serves as the administrative center.

The county was established in 1839 with Mount Carroll chosen as its administrative center for government operations. This designation made Mount Carroll the core of local governance.

Residents gather throughout the year for county fairs and community events where farming and local traditions play a central role. These gatherings shape the social fabric of the area.

The county seat of Mount Carroll houses the administrative building where permits, licenses, and official documents are processed Monday through Friday. This is the central location for all official matters.

Part of the territory includes Mississippi Palisades State Park featuring distinctive limestone cliffs along the river. These natural formations mark the eastern landscape of the county.
